BACKGROUND

Meloxicam, which has the structure:

is a nonsteroidal anti-inflammatory (NSAID) drug that exhibitsanti-inflammatory, analgesic, and antipyretic activities. The meloxicammechanism of action may be related to prostaglandin synthetase(cyclo-oxygenase, COX) inhibition which is involved in the initial stepsof the arachidonic acid cascade, resulting in the reduced formation ofprostaglandins, thromboxanes and prostacylin.

SUMMARY

Meloxicam and some other NSAIDs have poor aqueous solubility which mayreduce bioavailability and slow the onset of pain relief resulting fromtheir use. One means of increasing the solubility and bioavailability ofmeloxicam is through the use of cyclodextrins. Cyclodextrin (also knownas cycloamyloses) are generally cyclic polysaccharides which form abucket-like shape. Cyclodextrins help to increase bioavailability ofother molecules because cyclodextrins are hydrophobic on the inside andhydrophilic on the inside which helps to facilitate the transport ofmolecules. The naturally occurring cyclodextrins include six, seven, andeight glucose units (α, β, and γ-cyclodextrin, respectively). However,synthetic cyclodextrins containing more or less glucose units arepossible. In aqueous solutions, cyclodextrins can form complexes (i.e.,an inclusion complex) with drugs by incorporating the drug into thecenter/hydrophobic portion of the cyclodextrin ring; althoughcyclodextrin compounds are also known to aggregate around a drug in amicelle-type structure. This ability of cyclodextrins may allow them toact as carriers to increase the bioavailability of less soluble drugs.

DETAILED DESCRIPTION

Provided herein are dosage forms with NSAIDs (such as meloxicam) andcyclodextrin (optionally in an inclusion complex), and/or bicarbonate,and methods of treatment using the dosage form.

A dosage form may be given enterally including, but not limited to,oral, sublingual, or rectal delivery, or parenterally including, but notlimited to, intravenous, intramuscular, intranasal, or subcutaneousdelivery.

Some methods include administration of a product that combines an NSAIDthat is formulated with: a) a cyclodextrin and/or b) a buffering agent.In some embodiments, the method involves treating a patient with apharmaceutical formulation comprising meloxicam and a cyclodextrinand/or a carbonate/bicarbonate. Method embodiments may also includetreating a patient to increase the bioavailability of meloxicam in thepatient or increase the rate at which the meloxicam becomesbioavailable.

The combination of meloxicam, a cyclodextrin (such as SBEβCD), and abicarbonate (such as sodium bicarbonate) may substantially increase thesolubility and rate of absorption of meloxicam after oraladministration, while maintaining its extended plasma concentrationhalf-life in mammals, such as humans after oral administration.

The combination of meloxicam, a cyclodextrin (such as SBEβCD), and abicarbonate (such as sodium bicarbonate) may substantially increase theoral bioavailability of meloxicam in mammals, such as humans, after oraladministration.

Unless otherwise indicated, any reference to a compound herein, such asmeloxicam or rizatriptan, by structure, name, or any other means,includes pharmaceutically acceptable salts, alternate solid forms, suchas polymorphs, solvates, hydrates, enantiomers, tautomers,deuterium-modified forms, or any other chemical species, such asprecursors, prodrugs, or any other chemical species that may rapidlyconvert to a compound described herein under conditions in which thecompounds are used as described herein.

A subject combination may be given enterally including, but not limitedto, oral, sublingual, or rectal delivery, or parenterally including, butnot limited to, intravenous, intramuscular, intranasal, or subcutaneousdelivery. In some embodiments, both meloxicam and rizatriptan areadministered orally. In some embodiments, meloxicam is administeredintravenously and rizatriptan is administered orally. In someembodiments, meloxicam is administered intramuscularly and rizatriptanis administered orally.

Normally, the combination of meloxicam and rizatriptan is administeredso that the human being receives the meloxicam and rizatriptan within ashort period of time with respect to one another. For example, themeloxicam and rizatriptan may be administered within about 2 hours,within about 1 hour, within about 30 minutes, within about 20 minutes,within about 15 minutes, within about 10 minutes, within about 5minutes, or within about 1 minute of one another. In some embodiments,the meloxicam and rizatriptan are administered simultaneously, which forthe purpose of this disclosure includes administration within about 5minutes. In some embodiments, the meloxicam and rizatriptan areadministered in a single dosage form.

The term “treating” or “treatment” broadly includes any kind oftreatment activity, including the diagnosis, cure, mitigation, orprevention of disease in man or other animals, or any activity thatotherwise affects the structure or any function of the body of man orother animals.

The dosage form or the subject combination may be used to treat, orprovide relief of, any type of pain including, but not limited to,migraine and other types of headache, inflammatory pain, musculoskeletalpain, neuropathic pain, chronic pain, acute pain, localized pain,systemic pain, cancer-related pain, acute pain, pain due to injury, paindue to illness (e.g., fever), post-operative pain, etc. In someinstances, pain relief may be palliative, or pain relief may be providedindependent of improvement of the disease or condition or the underlyingcause of the disease or condition. For example, although the underlyingdisease may not improve, or may continue to progress, an individualsuffering from the disease may experience pain relief. In someembodiments, the pain affects a muscle, nerve, cartilage, bone,ligament, tendon, tendon sheaths, bursae, or joint.

Migraine is a disabling neurological disorder characterized by recurrentattacks of pulsating head pain accompanied by nausea and sensitivity tolight and sound. This pain may be moderate to severe, but is oftensevere and incapacitating, requiring bed rest. The headaches may affectone half of the head, may be pulsating in nature, and may last from 2 to72 hours. Associated symptoms may include nausea, vomiting, andsensitivity to light (photophobia), sound (phonophobia), or smell. Themigraine pain may be accompanied by disturbed vision. The migraine paincan be made worse by physical activity. Migraines may be associated withan aura, which may be a short period of visual disturbance which signalsthat the headache will soon occur. Some migraine patients may not haveaura.

In some embodiments, the human being who is being treated for migrainepain suffers from allodynia, such as cutaneous allodynia with theirmigraine attacks. Allodynia, such as cutaneous allodynia, which is painfrom normally non-painful stimuli (such as brushing hair, wearingglasses, taking a shower, etc.). Patients having allodynia, such ascutaneous allodynia are believed to be less likely to respond well totriptan medications.

Current treatments are suboptimal, with more than 70% of sufferersreporting dissatisfaction with existing acute treatments. The mostcommonly reported reasons for patient dissatisfaction are slow onset ofpain relief, inconsistent pain relief, and recurrence of pain during thesame day. Suboptimal acute treatment is associated with a significantlyincreased risk of new-onset chronic migraine, which may be prevented byimproving acute treatment outcomes.

Administering a subject combination to a human being suffering frommigraine, such as an acute attack of migraine pain or aura, may quicklyresult in a reduction in a migraine symptom, such as pain, nausea,vomiting, photophobia, or phonophobia, such as at or within about 5minutes (intended as a shorthand for “at about 5 minutes, or withinabout 5 minutes”), at or within about 10 minutes, at or within about 30minutes, at or within about 1 hour, at or within about 90 minutes, at orwithin about 2 hours, at or within about 2.5 hours, or at or withinabout 3 hours. In some embodiments, a human being experiences areduction of, or complete relief from, pain, such as headache pain ormigraine pain, nausea, vomiting, photophobia, and/or phonophobia, at orwithin about 1 hour, at or within about 90 minutes, at or within about 2hours, at or within about 2.5 hours, or at or within about 3 hours. Insome embodiments, the relief experienced, is greater than would beexperienced by receiving the same amount of rizatriptan withoutmeloxicam. In some embodiments, the relief experienced, is greater thanwould be experienced by receiving the same amount of meloxicam withoutrizatriptan.

The subject combination may be administered at the earliest sign ofmigraine pain, or soon after the earliest sign of migraine, such aswithin about 1 minute, within about 5 minutes, within about 10 minutes,within about 15 minutes, within about 20 minutes, within about 30minutes, or within about 1 hour. At this early state, the pain may stillbe mild, or before the pain progresses to moderate or severe intensity.For some methods, the subject combination may be administered when themigraine pain has reached moderate or severe intensity.

The combination of meloxicam and rizatriptan may have distinct dualmechanisms of action for the acute treatment of migraine. Meloxicam is apotent, COX-2 preferential NSAID which is limited by slow absorption.Rizatriptan is a potent 5-HT1_(B/D) agonist believed to have efficacy inmigraine.

Observation of relief or reduction in a symptom at a specific period oftime, such as “at 2 hours,” is useful because it allows theeffectiveness of the treatment to be evaluated at a specific orconsistent time point, which facilitates comparison between patients.Observation of relief or reduction in a symptom within a specific periodof time, such as “within about 2 hours,” is useful because it isdesirable for relief or reduction of a symptom to occur as early aspossible, and specifying that relief occur within a specified time setsa guideline in which it is desirable that relief occur.

For some methods, administration of the subject combination may achievea reduction in migraine pain, nausea, vomiting, photophobia, orphonophobia that lasts at least about one hour, at least about twohours, at least about three hours, at least about four hours, at leastabout six hours, at least about eight hours, about 8-24 hours, about 24hours, or more than 24 hours.

In some embodiments, enhanced bioavailability of the dosage form may beachieved in treating one of these conditions by administering a dosageform comprising a salt form of the meloxicam, by creating an inclusioncomplex with meloxicam and cyclodextrin, and/or by including abicarbonate. This may allow a reduced molar amount of the meloxicam tobe used as compared to other meloxicam dosage forms.

Unless otherwise indicated, any reference to a compound herein, such asmeloxicam or a cyclodextrin, by structure, name, or any other means,includes pharmaceutically acceptable salts, alternate solid forms, suchas polymorphs, solvates, hydrates, enantiomers, tautomers,deuterium-modified forms, or any other chemical species that may rapidlyconvert to a compound described herein under conditions in which thecompounds are used as described herein.

In some embodiments, use of a cyclodextrin, a carbonate, or abicarbonate may improve the oral bioavailability of meloxicam by atleast about 10%, at least about 20%, at least about 30%, at least about40%, at least about 50%, at least about 60%, at least about 70%, atleast about 80%, at least about 90%, up to about 100%, up to about 200%,or any amount in a range bounded by, or between, these values ascompared to administration of meloxicam alone.

Due to the improved bioavailability, the dosage form may contain, or asubject may receive, on a molar basis, less of the meloxicam than wouldotherwise be administered. For example, a dosage form may contain, or amammal may receive, at least about 10 mole % less, at least about 20mole % less, at least about 30 mole % less, at least about 40 mole %less, at least about 50 mole % less, at least about 60 mole % less, atleast about 70 mole % less, at least about 80 mole % less, at leastabout 85 mole % less, and/or up to about 90 mole % less, 95 mole % less,or any amount in a range bounded by, or between, these values as wouldotherwise be administered of meloxicam.

These doses may be a safe dose for repeated administration, suchas once hourly dosing to once daily dosing, twice daily dosing, dosingone to 12 times daily, doing 3, 4, 5, or 6 times daily, etc. In someembodiments, the meloxicam may be safely administered 2, 3, 4, 5, 6, 7,8, 9, 10, 11, 12, 13, 14, or 15 times, or about 3 to about 10 times aday, once a day, or less frequently, such as once a week, once every twoweeks, once a month, etc.

For some dosage forms, meloxicam forms a complex with thesubstituted-β-cyclodextrin or other another cyclodextrin which may beformulated into a solid dosage form. Such a dosage form may be suitablefor oral administration. A meloxicam-cyclodextrin inclusion complex mayalso be dissolved in water or another solvent to form a parenteralformulation. However, physical mixtures of meloxicam and thesubstituted-β-cyclodextrin or other cyclodextrins may also be used inoral or parenteral dosage forms.

Formation of an inclusion complex of meloxicam and a cyclodextrin mayhelp to improve the properties of a dosage form. For some inclusioncomplexes, the meloxicam and the cyclodextrin (e.g., SBEβCD) may have amolar ratio of about 0.5-2 (a molar ratio of 0.5 is 0.5 moles ofmeloxicam to 1 mole of cyclodextrin), about 0.5-0.7, about 0.6-0.8,about 0.7-0.9, about 0.8-1, about 0.9-1.1, about 1-1.2, about 1.1-1.3,about 1.2-1.4, about 1.3-1.5, about 1.4-1.6, about 1.5-1.7, about1.6-1.8, about 1.7-1.9, about 1.8-2, about 0.8-1.2, about 1, or anyratio in a range bounded by any of these values.

For some dosage forms, a cyclodextrin (e.g., SBEβCD) may be employed ina weight ratio to the meloxicam within the range from about 1-1000 (e.g.1 g of cyclodextrin per 1 g of meloxicam is a weight ratio of 1); about1-20; about 1-10; about 1-15; about 2-4, about 3-5, about 4-6, about5-7, about 6-8, about 7-9, about 8-10, or any weight ratio in a rangebounded by, or between, any of these values. For some dosage forms, acyclodextrin (e.g., SBEβCD) may be employed in a weight ratio to themeloxicam within the range from about 0.001-1 (e.g. 0.1 g ofcyclodextrin per 1 g of meloxicam is a weight ratio of 0.1); about0.01-1; about 0.05-1; about 0.1-1; about 0.2-1; about 0.3-1, about0.4-1, about 0.5-1, about 0.6-1, about 0.7-1, about 0.8-1, or any weightratio in a range bounded by, or between, any of these values. Each typeof cyclodextrin employed may have a different ratio.

For some dosage forms, the cyclodextrin may be present in an amount fromabout 1-200 mg; 25-175 mg; about 50-150 mg; about 25-100 mg; about75-150 mg; about 100-175 mg; about 20-80 mg; about 25-50 mg; about60-100 mg; about 80-100 mg; about 80-120 mg; about 100-120 mg; about100-140 mg; about 120-160 mg; about 140-180 mg; about 30-90 mg; about40-80 mg; about 50-70 mg, about 55-65 mg, about 60-62 mg, or any amountin a range bounded by, or between, any of these values.

The weekly dose may be given as a single dose, given onceduring the week, or may be given in 2, 3, 4, 5, 6, or 7 individual dosesduring the week.

In some embodiments, the monthly dose of meloxicam (e.g., an oral dose),or a dose administered over a period of a month, is about 5000 mg orless; about 4000 mg or less; about 3000 mg or less; about 2000 mg orless; about 1000 mg or less; about 700 mg or less; about 600 mg or less;about 1-4000 mg; about 1-1000 mg; about 10-1000 mg; about 50-1000 mg;about 10-600 mg; about 40-600 mg; about 50-600 mg; about 40-400 mg;about 50-200 mg; about 200-240 mg; about 240-280 mg; about 280-320 mg;about 320-360 mg; about 360-400 mg; about 400-450 mg; about 450-500 mg;about 500-600 mg; about 250-350 mg; about 100-600 mg; about 40-2000 mg;about 40-800 mg; about 100-900 mg; about 100-800 mg; about 40-1000 mg;about 50-1000 mg; about 100-1000 mg; or any monthly dose in a rangebounded by, or between, any of these values. A monthly dose may be givenas a single dose, or as two or more individual doses administered duringthe month. In some embodiments, the monthly dose is administered in 2 or3 bi-weekly doses. In some embodiments, the monthly dose is administeredin 4 or 5 weekly doses. In some embodiments, the monthly dose isadministered in 28 to 31 daily doses, or in 56 to 62 daily doses ormore. In some embodiments, the monthly dose is administered in 5 to 15individual doses during the month. The monthly dose may be administeredfor only 1 month, or may be repeatedly administered for 2 or moremonths.

In other embodiments, the dosage form may be administered weekly forabout one, two, three, four, or more consecutive weeks, every other weekor bi-weekly, or once every three weeks. This regimen may be repeatedonce weekly, twice in a month, three times in a month, once monthly,once every two months, once every three months, or as directed by amedical professional.

In certain embodiments, the pharmaceutical composition results inincreased bioavailability (e.g., reduced T_(max), increased C_(max),increased AUC, etc.) of the meloxicam from the dosage form as comparedto a dosage form containing meloxicam but not containing a cyclodextrin,an acid inhibitor, or a buffering agent (such as a bicarbonate). In someembodiments, the bioavailability of meloxicam will increase withmultiple dosing. For example, the bioavailability of meloxicam in thedosage form may increase after about 1-10 days of dosing; about 2-6 daysof dosing; about 3-5 days of dosing; about 4-6 days of dosing; about 5-8days of dosing; about 5 days of dosing; about 6 days of dosing; about 7days of dosing; about 8 days of dosing; about 10 days of dosing; about15 days of dosing; or time in any range bounded by, or between, any ofthese values; as compared to the bioavailability of meloxicam in adosage form not containing a cyclodextrin, an acid inhibitor, or abuffering agent (such as a bicarbonate).

Some of the dosage forms may result in a desired range for an area underthe plasma concentration curve (AUC) of meloxicam. For example thedosage with meloxicam may result in an AUC of meloxicam of about 1-150μg·hr/nnL; about 10-30 μg·hr/nnL; about 20-40 μg·hr/nnL; about 30-50μg·hr/nnL; about 40-60 μg·hr/nnL; about 50-70 μg·hr/nnL; about 60-80μg·hr/nnL; about 70-90 μg·hr/nnL; about 80-100 μg·hr/nnL; about 10-100μg·hr/nnL; about 50-150 μg·hr/nnL; about 25-125 μg·hr/nnL; about 75-150μg·hr/nnL; about 20-50 μg·hr/nnL; about 40-70 μg·hr/nnL; about 60-90μg·hr/nnL; about 80-110 μg·hr/nnL; about 100-130 μg·hr/mL; about 120-150μg·hr/mL; or any AUC in a range bounded by, or between, any of thesevalues.

Unless otherwise indicated, the AUC refers to the AUC calculated to thelast measured concentration (AUC_(0-t)), such as, over a period of 6hours (AUC₀₋₆), over a period of 12 hours (AUC₀₋₁₂), over a period of 24hours (AUC₀₋₂₄), or extrapolated to infinity (AUC_(0-inf)).

In Example 3 below, the AUC₀₋₂₄ of meloxicam in human beings for an oraldosage form containing sodium bicarbonate and sulfobutyletherβ-cyclodextrin (SBEβCD) was about 27 μg·hr/mL. This dosage formcontained 15 mg of meloxicam.

The 15 mg IV and intramuscular doses also provide an AUC₀₋₂₄ ofmeloxicam in human beings that is about 27 μg·hr/mL. The AUC ofmeloxicam is believed to be approximately dose proportional. So for thisoral dosage form, or for an IV or intramuscular dosage form, a meloxicamdose of, for example, approximately 17 mg to about 30 mg would beexpected to result in an AUC₀₋₂₄ of meloxicam of about 30-50 μg·hr/mL.

For some acute pain conditions, such as migraine and other types ofheadache, the AUC for a short period after oral administration, such asan AUC measured over 6 hours (or AUC₀₋₆), may be of particular interest.For example, some dosage forms may result in an AUC₀₋₆ of at least about6 μg·hr/mL; at least about 7 μg·hr/mL; at least about 8 μg·hr/mL; atleast about 9 μg·hr/mL; about 6-10 μg·hr/mL; about 7-11 μg·hr/mL; about8-12 μg·hr/mL; about 9-13 μg·hr/mL; or any AUC in a range bounded by, orbetween, any of these values.

In some embodiments, the dosage form may result in a C_(max) ofmeloxicam of about 10-2500 ng/mL; about 100-2250 ng/mL; about 500-2000ng/mL; about 1000-2500 ng/mL; about 1000-2000 ng/mL; about 100-900ng/mL; about 750-1500 ng/mL; about 1250-2000 ng/mL; about 1500-2300ng/mL; about 800-1200 ng/mL; about 1900-2400 ng/mL; about 50-500 ng/mL;about 400-950 ng/mL; about 900-1500 ng/mL; about 1100-2200 ng/mL; about1300-1600 ng/mL; about 1200-1500 ng/mL; about 1400-2100 ng/mL; about1500-1900 ng/mL; about 1600-2100 ng/mL; about 1700-2000 ng/mL; about1800-2000 ng/mL; about 1900-2500 ng/mL; about 150-1700 ng/mL; about1600-1800 ng/mL; about 1700-1900 ng/mL; about 1800-2000 ng/mL; about1900-2100 ng/mL; about 2000-2200 ng/mL; about 2100-2300 ng/mL; about2200-2400 ng/mL; about 2300-2500 ng/mL; about 2500-3000 ng/mL; or anyC_(max) in a range bounded by, or between, any of these values.

For acute migraines, the amount of meloxicam and/or rizatriptan in asingle dose, or the AUC of the meloxicam and/or rizatriptan associatedwith a single dose, is of particular interest. For example, after asingle dose, the symptoms may be relieved for an extended period oftime, such that, in the short term, repeated doses may not be needed.For more continuous conditions, including more chronic, continuous, orfrequent migraine symptoms, daily, weekly, or monthly doses may be ofparticular interest.

For any amounts of rizatriptan described herein, salt forms ofrizatriptan may be present in the amounts recited above, or amounts thatare molar equivalents to these amounts for the rizatriptan free base.For example, assuming that the molecular weight of rizatriptan free baseis 269.3 g/mol, 10 mg of rizatriptan is 37.1 mmol of rizatriptan. Thus,a molar equivalent of 10 mg of rizatriptan free base would be the massof 37.1 mmol of that salt form. For example, for the benzoate salt(mw=391.2 g/mol), the molar equivalent of 10 mg of the free base (or37.1 mmol), would be 14.5 mg. These doses may be safe for repeatedadministration, such as 1, 2, 3, or 4 times a day, or repeated at aninterval of 2 days, 3 days, 4 days, 5 days, 6 days, 7 days, 8 days, 9days, 10 days, 11 days, 12 days, 13 days, 14 days, 15 days, 16 days, 17days, 18 days, 19 days, 20 days, 21 days, 22 days, 23 days, 24 days, 25days, 26 days, 27 days, 28 days, 29 days, 30 days, 31 days, 4 weeks, 4-6weeks, about 1-2 months, about 6 weeks, about 2-3 months, about 3-4months, about 4-5 months, about 5-6 months, about 6-7 months, about 7-8months, about 8-9 months, about 9-10 months, about 10-11 months, about11-12 months, etc.

The componentsof the pharmaceutical composition may be in an immediate or extendedrelease form individually or in total.

The term “unit dosage form” as used herein refers to a single entity fordrug administration. For example, a single tablet or capsule combiningboth an acid inhibitor and an NSAID would be a unit dosage form. A “unitdosage form” (or “unit dose form”) may also be referred to as a “fixeddosage form” (or “fixed dose form”) or “fixed dosage combination” (or“fixed dose combination”) and are otherwise interchangeable. In oneembodiment, the unit dosage form is a multilayer tablet.

In another embodiment, the unit dosage form is suitable for oraladministration to a patient. In yet another embodiment, the unit dosageform is a tablet. In still another embodiment, the unit dosage form is amultilayer tablet comprising a single core and one or more layersoutside of the core.

Some dosage forms may comprise a first layer comprising meloxicam, anSBEβCD, and a bicarbonate; and a second layer comprising a secondtherapeutically active agent and a bicarbonate.

The first layer may contain, for example, any amount of meloxicam in oneof the ranges recited above. For example, all of the meloxicam in thedosage form may be present in the first layer. The second layer maycontain all of the second therapeutically active agent, such that anyamount in the ranges recited above with respect to the secondtherapeutically active agent may apply to the second layer.

In some embodiments, the first layer contains about 10-200 mg, about50-150 mg, about 50-100 mg, about 70-120 mg, about 90-140 mg, or about100 mg of the bicarbonate, such as sodium bicarbonate, or any amount ofthe bicarbonate in a range bounded by any of these values.

Example 1

The effect of varying amounts of potassium carbonate (K₂CO₃) and sodiumbicarbonate (NaHCO₃) on the pH of acidic media was tested. The acidicmedia was chosen to simulate gastric conditions. K₂CO₃ or NaHCO₃ wasadded to 50 mL of a 0.01 N HCl solution (pH 2). The pH of the solutionwas measured after addition of the K₂CO₃ or NaHCO₃. Deionized water (240mL) was then added to the mixture and pH was measured again. The resultsare shown in Tables 1-4.

Example 2

Tablets containing meloxicam and combinations of asulfobutylether-β-cyclodextrin (SBEβCD) (a cyclodextrin, containingabout 6 to about 7 sulfobutyl ether groups for each molecule ofβ-cyclodextrin), K₂CO₃, or NaHCO₃ were manufactured and tested fordissolution. Tablets containing meloxicam alone (MOBIC®) were purchasedand also tested for dissolution. The tested tablets are listed in Table5. Meloxicam in the form of meloxicam/SBEβCD inclusion complexes wasused in the tablets containing meloxicam and SBEβCD. The inclusioncomplexes were formed by mixing meloxicam and SBEβCD in an aqueouspH-adjusted solution. The pH of the solution was adjusted usingbuffering agents. The resulting soluble meloxicam/SBEβCD inclusioncomplexes were then spray dried. This spray-dried dispersion was used inthe manufacture of the tablets containing SBEβCD.

Dissolution testing in acidic medium (chosen to simulate gastricconditions) was performed by placing the tablets in a 0.01 N HClsolution, at an agitation rate of 75 RPM, and vessel temperature ofapproximately 37° C. The results are presented in Tables 6 and in FIGS.1-10. Results at various time points (0, 15, 30, 45, 60, 90, and 120minutes) are presented as percent (%) of meloxicam dissolved.

Dissolution of meloxicam was greater with the tablets containing variouscombinations of meloxicam and SBEβCD, K₂CO₃, or NaHCO₃, as compared totablets containing meloxicam alone. For example, after 120 minutes,dissolution of meloxicam tablets containing NaHCO₃ was 95% as comparedto 2% for tablets containing meloxicam alone.

Dissolution of meloxicam increases with increasing amounts of K₂CO₃ inthe absence of SBEβCD. However, in the presence of SBEβCD, increasingamounts of K₂CO₃ did not appear to increase meloxicam dissolution. Atthe highest dose of potassium carbonate tested, meloxicam dissolution inthe presence of SBEβCD was reduced by approximately 50% as compared tomeloxicam dissolution in the absence of SBEβCD at 120 minutes.

Dissolution of meloxicam with NaHCO₃ was significantly greater than thatobserved with the highest dose of K₂CO₃ at 15 minutes (50% versus 30%),and at 120 minutes (92% versus 23%). Meloxicam dissolution in thepresence of SBEβCD was also significantly greater with NaHCO₃ ascompared to the highest dose of K₂CO₃ at 15 minutes (85% versus 26%),and at 120 minutes (86% versus 12%). NaHCO₃ in the presence of SBEβCDincreased meloxicam dissolution more at 15 minutes as compared topotassium carbonate, which resulted in a reduction in dissolution.

Example 3

A bilayer tablet containing 1) an inclusion complex of SBEβCD withmeloxicam, prepared as described below, and 2) sodium bicarbonate wasprepared (SBEβCD-Meloxicam/Bicarbonate). The first layer contained aninclusion complex of 15 mg meloxicam and 100 mg SBEβCD, and 100 mg ofsodium bicarbonate. The second layer contained 40 mg of esomeprazole and400 mg of sodium bicarbonate.

A total of 20 human subjects were randomly assigned in a 1:1 ratio totreatment with the SBEβCD-Meloxicam/Bicarbonate tablets described aboveor Mobic® tablets (15 mg meloxicam), once daily for 6 days under fastingconditions.

On the first day of dosing, plasma samples were collected forconcentration analysis of meloxicam at several time points.Concentrations of meloxicam were determined using LC-MS/MS.Pharmacokinetic parameters were calculated. The results are depicted inFIG. 11.

The median T_(max) for meloxicam, the trial's primary endpoint, was 9times faster for the SBEβCD-Meloxicam/Bicarbonate tablets as compared toMobic® (0.5 hour versus 4.5 hours respectively, p<0.0001).

The SBEβCD-Meloxicam/Bicarbonate tablets also demonstrated higher meanmaximum plasma concentration (C_(max)) (p=0.0018), faster time totherapeutic plasma concentration (p<0.0001), and faster time tohalf-maximal plasma concentration (p<0.0001) as compared to Mobic®.

Meloxicam in the form of meloxicam/SBEβCD inclusion complexes was usedin the tablets containing meloxicam and SBEβCD. The inclusion complexeswere formed by mixing meloxicam and SBEβCD in an aqueous pH-adjustedsolution. The pH of the solution was adjusted using buffering agents.The resulting soluble meloxicam/SBEβCD inclusion complexes were thenspray dried. This spray-dried dispersion was used in the manufacture ofthe tablets containing SBEβCD.

Example 4

A monolayer tablet containing 1) the inclusion complex of SBEβCD withmeloxicam; 2) rizatriptan; and 3) sodium bicarbonate was prepared(SBEβCD-Meloxicam/rizatriptan/Bicarbonate). The monolayer tabletcontained 20 mg of meloxicam, 10 mg of rizatriptan, and 500 mg of sodiumbicarbonate. The inclusion complex was the same as the inclusion complexof Example 3.

Dissolution testing of the tablets in acidic medium (chosen to simulategastric conditions) was performed by placing the tablets in a 0.01 N HClsolution, at an agitation rate of 75 RPM, and vessel temperature ofapproximately 37° C. The results are presented in Table 7. Results atvarious time points (0, 15, 30, 45, 60, 90, and 120 minutes) arepresented as percent (%) of meloxicam, and percent (%) of rizatriptandissolved.

As shown in Table 7, the dissolution results of the tablets in Example 4are very similar to the dissolution result of Example 3. Therefore, weexpected the pharmacokinetic properties, including bioavailability,T_(max) of meloxicam, etc., of the tablets in Example 4 to be similar tothose described in Example 3 and FIG. 11. This expectation turned out tobe correct, as shown in the examples below.

Example 5

The monolayer tablet of Example 4 was administered to six humansubjects. On the first day of dosing, plasma samples were collected forconcentration analysis of rizatriptan at several time points.Concentrations of rizatriptan and meloxicam were determined usingLC-MS/MS. Pharmacokinetic parameters were calculated. The results formeloxicam were comparable to those reported for the bilayer dosage formof Example 3. The median T_(max) of rizatriptan was 0.75 hours and themean C_(max) of rizatriptan was 20.710 ng/mL. By comparison, thereported T_(max) of the commercial rizatriptan dosage form, Maxalt®, is1.0-1.5 hours.

Example 6

A Phase 1, randomized, single-dose, parallel-group clinical study wasconducted to evaluate the PK, safety and tolerability of 1) acombination of meloxicam (20 mg), rizatriptan (10 mg), SBEβCD, andsodium bicarbonate (meloxicam/rizatriptan), as compared to 2) andMaxalt® (10 mg rizatriptan), in healthy human volunteers after oraladministration under fasted conditions. A total of 20 healthy, adultmale or female volunteers were randomized in a 1:1 ratio to receive asingle dose of meloxicam/rizatriptan, or Maxalt® (10 mg rizatriptan).

Blood samples for PK analysis were collected pre dose and at multipletime points post dose. The pre-specified primary endpoint was T_(thera),the time to reach a therapeutic plasma concentration of meloxicam,defined as the C_(avg) of meloxicam after administration of the highestapproved dose (15 mg) of standard meloxicam, which is approximately 1000ng/mL. PK results for the rizatriptan component of meloxicam/rizatriptanwere compared to those for Maxalt® (rizatriptan).

PK results for the meloxicam (20 mg) component of meloxicam/rizatriptanfrom this trial were compared to PK results for Mobic® (15 mg meloxicam)from Example 3.

Phase 1 Results

Meloxicam was rapidly absorbed after oral administration ofmeloxicam/rizatriptan (20 mg meloxicam/10 mg rizatriptan), with a mediantime to therapeutic plasma concentration (T_(thera)) of 17 minutes, theprimary endpoint (FIG. 12 and Table 8). Median T_(max) was 1 hourcompared to 4.5 hours for 15 mg standard meloxicam (Mobic®). The veryshort T_(max) suggests the potential for meloxicam/rizatriptan to haverapid onset of action in treating migraine. Mean plasma eliminationhalf-life (T_(1/2)) for meloxicam was 18.2 hours after administration ofmeloxicam/rizatriptan, which compares to 21.5 hours for standardmeloxicam. The long elimination half-life suggests the potential formeloxicam/rizatriptan to enhanced and sustained efficacy, and to reducemigraine pain recurrence.

Example 7

A Phase 3, randomized, double-blind, multicenter, active- andplacebo-controlled trial is carried out to assess the efficacy andsafety of meloxicam/rizatriptan in the acute treatment of moderate andsevere migraine, in patients with a history of inadequate response toprior acute migraine treatments. Eligible patients are randomized in a2:2:2:1 ratio to treatment with meloxicam/rizatriptan (20 mgmeloxicam/10 mg rizatriptan, with SBEβCD and sodium bicarbonate asdescribed in Example 4 above), rizatriptan (10 mg) (rizatriptan arm),meloxicam (20 mg) with SBEβCD and sodium bicarbonate (meloxicam arm), orplacebo. Co-primary endpoints are freedom from headache pain, andfreedom from the most bothersome migraine-associated symptom (nausea,photophobia, or phonophobia), two hours after dosing, formeloxicam/rizatriptan as compared to placebo.

Superiority of meloxicam/rizatriptan to the rizatriptan and themeloxicam arms (component contribution) will be established based onsustained freedom from headache pain from 2 hours to 24 hours afterdosing (key secondary endpoint).

Eligible patients must have a history of inadequate response to prioracute migraine treatments, assessed using the Migraine TreatmentOptimization Questionnaire (mTOQ-4). The mTOQ-4 is a validatedquestionnaire that assesses efficacy response to prior acute treatmentsbased on four aspects (two-hour pain freedom, efficacy for at least 24hours with one dose, ability to plan daily activities, and disruption ofdaily activities).

It is expected that meloxicam/rizatriptan will show significantimprovement over placebo and superiority over the rizatriptan and themeloxicam arms because of the rapid absorption and distinct dualmechanisms of action of meloxicam/rizatriptan described herein.

Example 11

Over 37 million Americans suffer from migraine according to the Centersfor Disease Control, and it is the leading cause of disability amongneurological disorders in the United States according to the AmericanMigraine Foundation. Migraine is characterized by recurrent attacks ofpulsating, often severe and disabling head pain associated with nausea,and sensitivity to light and or sound. It is estimated that migraineaccounts for $78 billion in direct (e.g. doctor visits, medications) andindirect (e.g. missed work, lost productivity) costs each year in theUnited States [Gooch C L, Pracht E, Borenstein A R, The burden ofneurological disease in the United States: A summary report and call toaction. Ann Neurol. 2017 April; 81(4):479-484]. Published surveys ofmigraine sufferers indicate that more than 70% are not fully satisfiedwith their current treatment, that nearly 80% would try a new therapy,and that they desire treatments that work faster, more consistently, andresult in less symptom recurrence [(1) Smelt A F, Louter M A, Kies D A,Blom J W, Terwindt G M, van der Heijden G J, De Gucht V, Ferrari M D,Assendelft W J, What do patients consider to be the most importantoutcomes for effectiveness studies on migraine treatment? Results of aDelphi study. PLoS One. 2014 Jun. 16; 9(6):e98933, 6; and (2) Lipton RB, Stewart W F, Acute migraine therapy: do doctors understand whatpatients with migraine want from therapy? Headache. 1999; 39(suppl2):520-526].

The World Health Organization classifies severe migraine attacks asamong the most disabling illnesses, comparable to dementia, quadriplegiaand active psychosis [(1) Menken et al. Arch Neural. 2000; 57:418-420;and (2) Shapiro and Goadsby. Cephalalgia. 2007; 27:991-4]. Debilitatingpain, and the often-constant fear of the next migraine attack, damagefamily life, social life, and employment [Global Burden of DiseaseStudy. Lancet. 2017; 390:1211-1259]. Depression and anxiety are twice ascommon in people with migraine than in healthy individuals [Antonaci etal. J Headache Pain. 2011; 12:115-125]. Widespread misperception of theseriousness of migraine contributes to its under-recognition andunder-treatment [Global Burden of Disease Study. Lancet. 2017;390:1211-1259]. The majority of patients are not fully satisfied withtheir current treatment. Thus, there is an urgent need for newtreatments that provide improved efficacy for this serious neurologicaldisease.

A Phase 3, randomized, double-blind, multicenter, placebo- andactive-controlled trial was conducted to assess the efficacy and safetyof the combination of meloxicam and rizatriptan (meloxicam/rizatriptan)in the acute treatment of moderate and severe migraine. Eligiblepatients must have an age of 18 to 65 years, an established diagnosis(at least 1 year) of migraine with or without aura as defined by ICHD-3criteria, an average of 2 to 8 moderate to severe migraines per month,had a history of inadequate response to prior acute migraine treatments,assessed by a score of 7 using the Migraine Treatment OptimizationQuestionnaire (mTOQ-4) (the average score was 3.6), corresponding topoor response to prior acute treatments. Exclusion criteria includedcluster headaches or other types of migraines, chronic daily headache 15non-migraine headache days per month), history of significantcardiovascular disease, and uncontrolled hypertension. In addition to ahistory of inadequate response, enrolled patients exhibited a high rateof characteristics that are strongly associated with poor treatmentoutcomes including cutaneous allodynia (75.4%), severe migraine painintensity (41.2%), obesity (43.7%), and morning migraine (36.6%). Atotal of 1,594 patients were randomized in a 2:2:2:1 ratio to themonolayer tablet of Example 4 (20 mg meloxicam/10 mg rizatriptan, withSBEβCD and sodium bicarbonate), rizatriptan (10 mg), meloxicam (20 mg)with SBEβCD (MoSEIC Meloxicam), or placebo, to treat a single migraineattack of moderate or severe intensity. The two co-primary endpoints ofthe trial were the proportion of patients who are free from headachepain two hours after dosing, and the proportion of patients who nolonger suffered from their most bothersome migraine-associated symptom(nausea, photophobia, or phonophobia) two hours after dosing, formeloxicam/rizatriptan as compared to placebo. Superiority ofmeloxicam/rizatriptan to the rizatriptan and meloxicam arms (componentcontribution) was to be established based on sustained freedom fromheadache pain from two to 24 hours after dosing (key secondaryendpoint). The study was conducted pursuant to an FDA Special ProtocolAssessment (SPA). Rizatriptan, an active comparator in the trial, isconsidered to be the fastest acting oral triptan and one of the mosteffective medications currently available for the acute treatment ofmigraine. (Ferrari M D, Roon K I, Lipton R B, Goadsby P J. Oral triptans(serotonin 5-HT(1B/1D) agonists) in acute migraine treatment: ameta-analysis of 53 trials. Lancet. 2001 Nov. 17; 358(9294):1668-75.)

Meloxicam/rizatriptan provided rapid relief of migraine pain with thepercentage of patients achieving pain relief with meloxicam/rizatriptanbeing numerically greater than with rizatriptan at every time pointmeasured starting at 15 minutes, and statistically significant by 60minutes (p=0.04) (FIG. 14). The proportions of patients experiencingpain relief 1.5 hours after dosing were 60.5% for meloxicam/rizatriptancompared to 52.5% for rizatriptan and 48.3% for placebo (p=0.019,p=0.04, respectively versus meloxicam/rizatriptan) (FIG. 14). FIG. 14Ashows the percentage of subjects reporting pain relief over placebo formeloxicam, rizatriptan, and meloxicam/rizatriptan at 1.0 hour and 1.5hours.

Meloxicam/rizatriptan met the two regulatory co-primary endpoints bydemonstrating, with high statistical significance, a greater percentageof patients as compared to placebo achieving pain freedom (19.9% versus6.7%, p<0.001, FIG. 15), and absence of most bothersome symptom (36.9%versus 24.4%, p=0.002), 2 hours after dosing.

Superiority of meloxicam/rizatriptan to rizatriptan (active comparator)and MoSEIC™ meloxicam (component contribution) was established asspecified in the SPA, by the demonstration of a greater percentage ofpatients receiving meloxicam/rizatriptan achieving sustained painfreedom from 2 hours to 24 hours after dosing, compared to rizatriptan,MoSEIC™ meloxicam, and placebo (16.1%, 11.2%, 6.8% and 5.3%,respectively; p=0.038, p=0.001, and p<0.001, respectively versusmeloxicam/rizatriptan, FIG. 16A), the pre-specified key secondaryendpoint to demonstrate component contribution. About 80% of thepatients treated with meloxicam/rizatriptan who achieved pain freedom at2 hours maintained pain freedom through 24 hours. These resultsdemonstrated the significant improvement in pain freedom and superiorityof meloxicam/rizatriptan to rizatriptan in treating migraine.

Meloxicam/rizatriptan provided substantially greater and more sustainedmigraine pain relief compared to placebo and rizatriptan, whichtranslated to a significant reduction in rescue medication use formeloxicam/rizatriptan compared to placebo and rizatriptan. Thepercentage of patients experiencing sustained pain relief from 2 hoursto 24 hours after dosing was 53.3% for meloxicam/rizatriptan, comparedto 33.5% for placebo and 43.9% for rizatriptan (p<0.001, p=0.006,respectively versus meloxicam/rizatriptan) (FIG. 16B).

Sustained pain relief from 2 hours to 48 hours was also experienced by astatistically significantly greater proportion of meloxicam/rizatriptanpatients (46.5%), compared to placebo (31.1%) and rizatriptan (36.5%)patients (p<0.001, p=0.003, respectively versus meloxicam/rizatriptan)(FIG. 17B). FIG. 17D shows the percentage of subjects achievingsustained pain relief over placebo from 2 hours to 48 hours formeloxicam, rizatriptan, and meloxicam/rizatriptan. The sustained painfreedom from 2 hours to 48 hours was also experienced by a statisticallysignificantly greater proportion of meloxicam/rizatriptan patients(15.4%), compared to placebo (5.3%), and rizatriptan (8.8%), and MoSEIC™meloxicam (8.1%) patients (p<0.001, p=0.003, p=<0.001, respectivelyversus meloxicam/rizatriptan) (FIG. 17A). FIG. 17C shows the percentageof subjects achieving sustained pain freedom over placebo from 2 hoursto 48 hours for meloxicam, rizatriptan, and meloxicam/rizatriptan. About77% of patients treated with meloxicam/rizatriptan who achieved painfreedom at 2 hours maintained the pain freedom through 48 hours.

Rescue medication was used by 23.0% patients receivedmeloxicam/rizatriptan, compared to 43.5% patients received placebo and34.7% patients received rizatriptan (p<0.001 for each group versusmeloxicam/rizatriptan) (FIG. 18). About 77% of patients receivingmeloxicam/rizatriptan did not require rescue medication. These resultsdemonstrated the superiority of meloxicam/rizatriptan to rizatriptan, anactive comparator, in treating migraine.

Meloxicam/rizatriptan was statistically significantly superior torizatriptan on several other secondary endpoints, including PatientGlobal Impression of Change (PGI-C) (p=0.022), and return to normalfunctioning at 24 hours (p=0.027).

Some of the p-values for meloxicam/rizatriptan versus rizatriptan forvarious endpoints are listed in Table 10 below, demonstrating thestatistically significant superiority of meloxicam/rizatriptan overrizatriptan in treating migraine.

Given that Rizatriptan, an active comparator in the trial, is consideredto be the fastest acting oral triptan and one of the most effectivemedications currently available for the acute treatment of migraine, andthat this trial enrolled patients with difficult-to-treat migraine, theobserved treatment effects with meloxicam/rizatriptan that providedgreater and more lasting migraine pain relief than rizatriptan, ishighly significant. Many patients experience a suboptimal response totheir current acute migraine treatments, placing them at increased riskof headache related disability and progression to chronic migraine,factors associated with increased healthcare costs. The results of thisstudy suggest that meloxicam/rizatriptan may provide an importanttreatment option for people with difficult-to-treat migraine.

Meloxicam/rizatriptan was safe and well tolerated in the patientsstudied in the trial. The most commonly reported adverse events withmeloxicam/rizatriptan were nausea, dizziness and somnolence, none ofwhich occurred at a rate greater than placebo or greater than 3%. Therewas one serious adverse event in the meloxicam/rizatriptan arm which wasdeemed by the investigator not to be related to the study drug.

The results of this trial demonstrate the ability ofmeloxicam/rizatriptan to provide unique benefits to migraine patients,with fast, strong, and durable relief of migraine pain as compared to apotent active comparator, rizatriptan, in a stringently designed trialenriched with patients with difficult-to-treat migraine. These resultshave potentially important implications for patient care based on thehigh rate of inadequate response to and patient dissatisfaction withcurrent treatments.

Meloxicam/rizatriptan incorporates multiple mechanisms of action toaddress various migraine processes with the goal of providing enhancedeffectiveness. Meloxicam/rizatriptan is thought to act by inhibitingCGRP release, reversing CGRP-mediated vasodilation, and inhibitingneuro-inflammation, pain signal transmission, and central sensitization.The results of this trial validate this approach, demonstrating thatmeloxicam/rizatriptan can provide significant benefit that is greaterthan that of currently available treatments, even in patients withdifficult-to-treat migraine. Meloxicam/rizatriptan may be used for theacute treatment of migraine in adults with or without aura effectively.

Example 12

A Phase 3, randomized, double-blind, multicenter, placebo-controlledtrial was conducted evaluating the early treatment of migraine withmeloxicam/rizatriptan. A total of 302 patients were randomized in a 1:1ratio to treat a single migraine attack with a single dose ofmeloxicam/rizatriptan (20 mg meloxicam/10 mg rizatriptan, with SBEβCDand sodium bicarbonate as described in Example 4 above), or placebo, atthe earliest sign of migraine pain, while the pain was mild, beforeprogressing to moderate or severe intensity.

This clinical trial is different from the clinical trial in Example 11.The clinical trial of Example 11 enrolled only patients with a historyof inadequate response to prior acute treatments, with patients waitingto treat their attacks only when the migraine pain had reached moderateor severe intensity. The clinical trial in Example 11 is in contrast tothis clinical trial, which enrolled all comers and in which patientswere instructed to administer meloxicam/rizatriptan at the earliest signof migraine pain while the pain was mild, before progressing to moderateor severe intensity.

The patients were adult subjects with an established diagnosis ofmigraine with or without aura.

Co-primary endpoints are freedom from headache pain, and freedom fromthe most bothersome migraine-associated symptom (nausea, photophobia, orphonophobia), two hours after dosing, for meloxicam/rizatriptan ascompared to placebo.

Secondary endpoints included sustained pain freedom, freedom frommigraine pain progression, change in functional disability, and use ofrescue medication.

Inclusion criteria included male or female at ages 18-65 inclusive, anestablished diagnosis (at least 1 year) of migraine with or without auraas defined by the ICHD-3 criteria, and an average of 2 to 8 migrainesper month. Exclusion criteria included cluster headaches, tensionheadaches, or other types of migraines, chronic daily headache (≥15non-migraine headache days per month), history of significantcardiovascular disease, and uncontrolled hypertension.

Meloxicam/rizatriptan substantially and significantly eliminatedmigraine pain, and substantially and significantly prevented progressionof migraine pain intensity in this Phase 3 trial ofmeloxicam/rizatriptan in the early treatment of migraine. In the trial,meloxicam/rizatriptan met the co-primary endpoints of freedom frommigraine pain and freedom from most bothersome symptoms as compared toplacebo.

Meloxicam/rizatriptan demonstrated statistically significant improvementas compared to placebo on both of the co-primary endpoints of painfreedom (32.6% versus 16.3%, p=0.002), and freedom from most bothersomesymptom (43.9% versus 26.7%, p=0.003), 2 hours after dosing (FIG. 19Aand FIG. 19B). The most bothersome symptom is nausea, photophobia, orphonophobia.

Meloxicam/rizatriptan was numerically superior to placebo as early as 30minutes for migraine pain freedom (FIG. 20) and most bothersome symptomfreedom (FIG. 21), achieving statistical significance for migraine painfreedom at 90 minutes (p=0.003) and at every time thereafter (FIG. 20).At 12 hours, 64% of the patients receiving meloxicam/rizatriptan werepain free as compared to 42% of patients receiving placebo. At 24 hours,69% of patients receiving meloxicam/rizatriptan were pain free ascompared to 47% of patients receiving placebo.

Meloxicam/rizatriptan durably relieved migraine pain with astatistically significantly greater percentage of patients as comparedto placebo achieving sustained pain freedom from 2 to 24 hours afterdosing (22.7% versus 12.6%, p=0.030), and from 2 to 48 hours afterdosing (20.5% versus 9.6%, p=0.013) (FIG. 22A and FIG. 22B).

Meloxicam/rizatriptan prevented progression of migraine pain intensitybeyond mild in 73.5% of patients versus 47.4% of patients taking placebofrom 2 to 24 hours (p<0.001) (FIG. 23). A single dose ofmeloxicam/rizatriptan prevented migraine pain progression beyond mild.

The effect on pain progression translated to a significant reduction inthe use of rescue medication, with only 15.3% of patients takingmeloxicam/rizatriptan required rescue medication through 24 hours afterdosing, versus 42.2% of patients taking placebo (p<0.001) (FIG. 24).

Meloxicam/rizatriptan substantially and significantly reduced functionaldisability, and demonstrated overall disease improvement. The ability toperform normal activities was achieved by 73.5% of patients takingmeloxicam/rizatriptan compared to 47.4% of patients taking placebo at 24hours (p<0.001) (FIG. 25).

On the Patient Global Impression of Change (PGI-C) scale, 52.4% ofpatients taking meloxicam/rizatriptan were very much or much improvedcompared to 27.7% of patients taking placebo (p<0.001) at hour 2 (FIG.26).

Meloxicam/rizatriptan was generally safe and well tolerated in thetrial. The most commonly reported adverse events withmeloxicam/rizatriptan were somnolence, dizziness, and paresthesia, allof which occurred at a rate of less than five percent (Table 11). Therewere no serious adverse events in the trial.

“[This] study demonstrated high rates of freedom from migraine pain withmeloxicam/rizatriptan treatment, and utilized an innovative design toevaluate migraine pain progression. It is remarkable that earlytreatment with meloxicam/rizatriptan prevented migraine pain progressionin the vast majority of patients and enabled a similarly high percentageof patients to return to normal functioning,” said Dr. Stewart Tepper,Professor of Neurology at the Geisel School of Medicine at Dartmouth.“The multiple mechanisms of meloxicam/rizatriptan address the manydisordered physiological processes implicated in migraine attacks. Theseresults, coupled with previous clinical data showing superiority ofmeloxicam/rizatriptan over an active comparator, provide clinicalevidence that this synergistic, multi-mechanistic approach and the rapidabsorption of meloxicam/rizatriptan may translate to important benefitsfor a wide range of patients. As clinicians continue to seek options fortheir patients with improved efficacy over currently availabletherapies, meloxicam/rizatriptan may offer an important new treatmentfor this disabling condition.”

This Phase 3 trial confirmed the superior and durable efficacy ofmeloxicam/rizatriptan. The prevention of migraine pain progression, andthe substantial increase in the rate of pain freedom demonstrated withearly treatment with meloxicam/rizatriptan, expands and enhances itsdifferentiated profile for the acute treatment of migraine. With thisPhase 3 trial and the Phase 3 trial described in Example 11 in patientswith a history of inadequate response to prior acute treatments,meloxicam/rizatriptan has now been evaluated in two positivewell-controlled trials. These trials demonstrated the efficacy ofmeloxicam/rizatriptan against potent active and placebo comparators,across a spectrum of migraine attack settings, regardless of the timingof migraine treatment, disease severity, or baseline pain intensity.

“Migraine is one of the most disabling disorders, incapacitatingsufferers and seriously damaging home life, social activity and theability to work. Published surveys have underscored that patients remaindissatisfied with the efficacy of currently available therapies,” saidCedric O'Gorman, MD, Senior Vice President of Clinical Development andMedical Affairs of Axsome. “The results of [this] trial demonstrate forthe first time that meloxicam/rizatriptan can halt migraine painprogression before reaching moderate or severe intensity. These datagrow the body of clinical evidence in support of the potential ofmeloxicam/rizatriptan to be a multi-mechanistic treatment for migrainewith efficacy that is superior to the current standard of care, andwhich can rapidly, robustly, and durably alleviate symptoms, and returnpatients to their normal daily activities.”
